Final answer:
The correct tool for creating a customized list of common utilities is the Microsoft Management Console (MMC) which enables the customization and organization of administrative tools in one console.
Step-by-step explanation:
If a technician wants to create a customized list of common utilities that are easily accessible in one place, they should use the Microsoft Management Console (MMC). This tool allows the creation of custom-made consoles which can include various snap-ins, such as device manager, disk management, and other administrative tools, that the technician uses regularly.
MSCONFIG is used for system configuration, MSTSC stands for Microsoft Remote Desktop Connection, and MSINFO32 opens System Information, none of which are used for the purpose of creating a list of utilities.
Therefore, B. MMC is the correct answer to the question.
